"Key criteria for which location will be the FIFO hub will be purely based on where the largest numbers of workers come from," he said.

"The South Burnett's large resource sector workforce gives the region an advantage."

About 1200 people from the Wide Bay Burnett have registered their interest or support for FIFO.

The concept was given a boost earlier this week when the regional development organisation secured a commitment from coal mining company GVK Hancocks to investigate establishing flight services in the Wide Bay Burnett.

But Mr Massingham urged those interested in FIFO coming to Kingaroy to express their interest online.

"It all comes down to the numbers of workers," he said.

"We need as many registrations as possible, for this to go ahead. If we can prove the demand is there, then the flights will turn up. It is quite as simple as that.

"For local airports to be used, there needs to be commercial viability to come to those towns."

The FIFO flight services proposed by the organisation would be for the Alpha Coal and Kevin's Corner projects. The three-year construction phase for the two projects required 6000 workers.

Mr Massingham said the response for FIFO in the Wide Bay Burnett area had been overwhelming.

"The 1200 responses have been fantastic, considering other organisations have done similar campaigns for FIFO in their regions with responses of just 60 or 80 people."

In the coming months Wide Bay Burnett airport infrastructure will be assessed. Kingaroy's airport does meet the standard for FIFO, Mr Massingham said.

"The Kingaroy airport absolutely meets the criteria," he said. "(But) all airports across the region will be considered as part of the assessment.

"The project is so large, they will need services from very large aircraft to smaller aircraft for the more remote areas."
